New techniques I'm bored with just stroking up and down help

I'm a 13 year old who is probably too turned on for his own good so yeah here's the thing I usually masturbate 7-8times a day orgasming and usually ejaculating every time so I can  actually orgasm and ejaculate about 3 times in a row without resting needless to say I have a very powerful sex drive.I was really turned on about 2 weeks ago this wasn't just turned on I was so turned on I actually had two go at it right then and there but after about 45 minutes I still couldn't come so I tried like a week later and still couldn't come  Now I get huge boners when I see girls especially my girlfriend and I don't want her to think I'm only with her to get in her pants I mean don't get me wrong I fantasize all the time ... about her but I love her and neither of us believe in premarital so I guess I need some new more kinky techniques. Also I need some easy and sneaky tips for lube I can get without telling my parents or sneaking to the store. P.S. don't say use fruit already tried that
